Pelosi calls Obama's Iran deal 'a diplomatic masterpiece'

House Minority Leader Nancy Pelosi said she believes Democrats will be able to uphold President Obama's veto if Republicans vote down his nuclear deal with Iran in September and she called the agreement "a diplomatic masterpiece."

Pelosi, D-Calif., said Democrats will rally behind the agreement even after the long August recess, when outside groups plan a media blitz aimed at sinking public support.

"More and more [Democrats] have conferred to me they will be there to sustain the veto," Pelosi told reporters on Thursday.

Congress has begun a 60-day review of the deal, which would lift sanctions against Iran in exchange for a reduction in its nuclear weapon capability. Republicans mostly oppose the agreement and with majorities in both the House and Senate, will likely garner enough votes to back a disapproval of the deal.
